What causes dog seizures, coordination loss, and brain infections?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 75 lbs

Today we had to put our dog down. He began seizing more and also lost coordination in his back end. Our vet believes it was and infection in the brain, or a disease of the brain. He believed it was his cerebellum that was affected. What diseases or infections would be most likely to cause this and is their any prevention for other pets. He did say it could have been something he was predisposed to as well.

I am sorry to hear of your loss - it is very upsetting to have to put a dog to sleep following such a traumatic illness. There are unfortunately many potential causes of seizures including parasitic, inflammatory and viral infection of the brain, tumours and birth defects. A full post mortem exam would be required in order to determine the exact cause. There are blood tests for diseases such as toxoplasma and neospora but be aware that you could test for multiple possibilities and still not find the cause or could indeed have a sample test positive for exposure to a disease which had no influence on the condition
